 * 1. Types and Components of a Computer System**
 * There is no denying that computers have changed and shaped our society, so much so we live in the 'Information Age'. There have been a lot of key dates that brought about our digital lives and it was an event in 1971 that really moved us forward with leaps and bounds and the dyanmice and every changing world of computing is hard to keep up with at times. Developments in ICT in 2012 are taking us to places that science fiction of the past could only dream of.

 * What is so special about a bit, especially a 4 bit?**

[]
 * Life has moved on since then and most computers run on 32 bit, also 64 bit can be found. However, the 4bit is still used in items such as washing machines, televisions and microwaves as well as other items.**
 * Thinking time???**
 * Why do you think a 4bit can still work for a washing machine and why has the laptop/desktop increased in bit processing up to as much as 64bit?**


 * The Microprocessor (the word Micro means small in Greek), was commercially available since 1971. This meant that the first comercial product could be made for a mass market and for the first time those who had the money could by a product for their own needs. The pocket calculator was a fantastic tool and 10 fingers were soon lost in the mists of time.. (metaphorically of course!).**
